Color-sorting metalenses boost imaging sensitivity

Researchers have shown that newly designed pixel-scale metasurface lenses—flat surfaces that use nanostructures to manipulate light—can be used to make imaging sensors that are roughly three times more sensitive than ...

New algorithms give digital images more realistic color

If you've ever tried to capture a sunset with your smartphone, you know that the colors don't always match what you see in real life. Researchers are coming closer to solving this problem with a new set of algorithms that ...
